Golang 1.25.x < 1.25.6 Multiple Vulnerabilities critical Nessus Plugin ID 294961 Language: Synopsis An application installed on the remote host is affected by multiple vulnerabilities. Description The version of Golang running on the remote host is 1.25.x prior to 1.25.6. It is, therefore, affected by multiple vulnerabilities as referenced in advisory. - bypass of flag sanitization can lead to arbitrary code execution. (CVE-2025-61731) - unexpected code execution when invoking toolchain. (CVE-2025-68119) - crypto/tls: Config.Clone copies automatically generated session ticket keys, session resumption does not account for the expiration of full certificate chain(CVE-2025-68121) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number. Solution Upgrade to Golang Go version 1.25.6 or later.
